RAILWAY-TIE.

Iatented Dec. 10, 1907.

Application filed April 1907- Serial No. 369,266.

'known as the reinforced concrete or cement type, wherein the body of the tie is composed of concrete or like plastic material, molded in and around metallic strengthening members. v

An object-of the invention is to rovide tie of thetype -described,in which t 6111613311 lic strengthening members are so disposed as to .bestresist fracture against the working strains and stresses.

Another object is toiurnish rail seats and fastenings adaptable for bothtangentand curve, and reinforceable when the situation" requires without alter'ationor undue multiplying of parts.

' This invention consists in the matters here-' inafter S6t".f01'tll, "and more particularlypointed out in the ap ended claims.

= Referring-to the rawings, Figure Tie a View in 'erspectiveof portions of'rails, and

a tie em odyxing features of the invention, partially bro en away to-give'view oftreinorcing member's, rail seat and locking bolts.

.Fig. 2 is a view in longitudinal sectionthrough a rail seat, showing the lockingbolts and drain. Fig.3 is a view showing t of additional locking bOItsoutside'of the.-

body of'the tie.

The upper face of the tie is provided with recesses 5, near each end of the tie, extending well down into the tie and having a draining duct dleading from the recess bottom through the tie. Arail seat Zis secured on the face of the tie over each-recess and mayconsist of 1 any suitable design which furnishes depending lateral lugs 3 which are adapted to grip, the sides of the tie and so prevent lateral dis-- placement, or may preferably. comprise a arallel pieces of inverted channelerein illustrated, Whose flan es grip the sides of thetie and the margins o the re-.,

pair of iron, as

' cess mouth. A transversely disposed cross pin Sis embedded near each end of the tie so;

as to, pass through each aperture near the bottom, its projecting ends being upset for i provide I Means for holding the rails in place on the seat comprise a pair of obliquely dis osed i'etainin heads, or else screw-threaded and w th nuts. 1

provided with nuts to retain the, parts in place." a The body of the tie is reinforced by'a lu- It is further, strengthene between the railseat recesses by an outer setof cable loops 16 whoseupper, central, unbroken portions are i "ralityfof straight pieces of cable 15 embe ded near eachcorner, runnin from end to end.

convex and whose lower'end portions lie straight and overla each other, the extreme 7 ends being inturne if so desired,.-and a con-. centrically' disposed innerset, of loops'- 1;7' similarly arranged.

To reinforce the body of" the tiei around each recess and, cross-pin, to preyentf-fracture or tearing ofi of the up or face of theftie,

al'special disposition of ca le loops is used.

Th s consists. ofgan outer set of parallel 1 ips .18,'whose lower central portions-pass under the recess'in'a pendant orcurve, and whose:

upper end portions are-laid horizontally over the crosslpinwiththeends in overlapping.

this outer set, and below the cross-pin, their ends being inturned' to 'form hooks'ZO which aidin retaining them in place. If desired, an auxiliary set vof cable art or fopen loops 21' maybe likewise, embed ed within the others i and above '..the crossins.
